Imaging Apparatus Repair for Corrupted Moving Image Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face issues with corrupted moving image files due to incomplete meta information generation, leading to unreproducible files if a hang-up occurs during recording, as seen in JP 2013-258655 A.
Innovation Solution
The imaging apparatus includes an image sensor, controller, and output interface to analyze and repair corrupted moving image files by generating a reproducible file based on remaining data, allowing partial output during repair processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repair processing is performed on corrupted moving image files, then file recoverability is improved, but processing time increases
Solution Approach 1:
The patent implements partial repair processing where the controller repairs only the necessary portions of corrupted moving image files (such as metadata sections) rather than attempting to reconstruct entire files. This selective approach recovers usable content while minimizing processing time, allowing users to retrieve at least portions of their footage even when files are partially corrupted.
2Loss of information
If complete repair processing is performed on all corrupted files, then data recovery is improved, but device availability deteriorates
Solution Approach 1:
The system performs preliminary damage assessment and triage on corrupted files, identifying which files can be quickly repaired and which require extensive processing. By prioritizing repair of files with higher recovery potential and lower processing requirements, the system recovers usable data faster while maintaining device availability for ongoing operations.
3Reliability
If repair processing is performed on corrupted files, then file usability is improved, but processing complexity increases
Solution Approach 1:
The patent divides corrupted moving image files into separate segments or sections (such as metadata portions and media data portions) and processes each segment independently. This segmentation allows the controller to apply targeted repair techniques to specific corrupted areas without attempting to reconstruct entire files, reducing processing complexity while improving overall file usability.
Data Source
AI summary
An imaging apparatus includes an image sensor, a controller, and an output interface. The image sensor captures a subject image to generate imaging data. The controller performs repair processing to generate a moving image file by sequentially analyzing information used for reproduction of a moving image from a corrupted file, the moving image file being capable of reproducing the moving image indicated by the imaging data, the corrupted file having a defect corrupted from the moving image file. The output interface outputs information to be presented to a user. The controller outputs a part of the moving image via the output interface, in a period from start of the repair processing on the corrupted file to completion of the repair processing, based on analyzed information in the repair processing in execution, the part of the moving image corresponding to the analyzed information.
